  Designation: A 217/A 217M – 01  Endorsed by Manufacturers Standardization Societyof the Valve and Fittings IndustryEndorsed by American Foundrymen’s SocietyUsed in USDOE-NE StandardsAn American National Standard Standard Specification for Steel Castings, Martensitic Stainless and Alloy, forPressure-Containing Parts, Suitable for High-TemperatureService 1 This standard is issued under the fixed designationA 217/A 217M; the number immediately following the designation indicates the yearof srcinal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon ( e ) indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. 1. Scope 1.1 This specification 2 covers martensitic stainless steel andalloy steel castings for valves, flanges, fittings, and otherpressure-containing parts (Note 1) intended primarily forhigh-temperature and corrosive service (Note 2).1.2 One grade of martensitic stainless steel and nine gradesof ferritic alloy steel are covered. Selection will depend ondesign and service conditions, mechanical properties, and thehigh-temperature and corrosion-resistant characteristics (Note3). N OTE  1—Carbon steel castings for pressure-containing parts are cov-ered by Specification A 216/A 216M. Low alloy quench-and-temperedgrades equivalent to Specification A 217/A 217M grades may be found inboth Specifications A 352/A 352M and A 487/A 487M.N OTE  2—The grades covered by this specification represent materialsthat are generally suitable for assembly with other castings or wroughtsteel parts by fusion welding. It is not intended to imply that these gradespossess equal degrees of weldability; therefore, it is the responsibility of the purchaser to establish for himself a suitable welding technique. Sincethese grades possess varying degrees of suitability for high-temperatureand corrosion-resistant service, it is also the responsibility of the purchaserto determine which grade shall be furnished, due consideration beinggiven to the requirements of the applicable construction codes.N OTE  3—The committee formulating this specification has includednine grades of materials that are considered to represent basic types of ferritic alloy steels suitable for valves, flanges, fittings, and other pressure-containing parts.Additional alloy steels that may better fulfill certain typesof service will be considered for inclusion in this specification by thecommittee as the need becomes apparent. 1.3 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard. Within the text, theSI units are shown in brackets. The values stated in eachsystem are not exact equivalents; therefore, each system mustbe used independently of the other. Combining values from thetwo systems may result in nonconformance with the specifi-cation. Inch-pound units are applicable for material ordered toSpecification A 217 and SI units for materials ordered toSpecification A 217M. 2.

Chemical Composition 6.1 The steel shall conform to the requirements as tochemical composition prescribed in Table 1. 7. Tensile Requirements 7.1 Steel used for the castings shall conform to the require-ments as to tensile properties prescribed in Table 2. 8. Quality 8.1 The surface of the casting shall be examined visuallyand shall be free of adhering sand, scale, cracks, and hot tears.Other surface discontinuities shall meet the visual acceptancestandards specified in the order. Practice A 802/A 802M orother visual standards may be used to define acceptable surfacediscontinuities and finish. Unacceptable visual surface discon-tinuities shall be removed and their removal verified by visualexamination of the resultant cavities. When methods involvinghigh temperature are used in the removal of discontinuities,castings shall be preheated to at least the minimum tempera-tures in Table 3.8.2 When additional inspection is desired, SupplementaryRequirements S4, S5, and S10 may be ordered.
